Powertrain & Engine Architecture
At the heart of the GLC 63 S lies the M177.980 4.0-liter V8 engine. This engine, a staple in many AMG models, utilizes a “hot-vee” configuration, meaning the turbochargers are located within the V of the engine block. This design minimizes turbo lag and improves responsiveness. The engine employs direct fuel injection, delivering fuel directly into the combustion chambers for precise control and increased efficiency. The valvetrain features four valves per cylinder, optimized for high-flow performance. The engine is paired with AMG’s SPEEDSHIFT MCT 9-speed automatic transmission. “MCT” stands for Multi Clutch Technology, a wet-start clutch system that replaces the traditional torque converter found in conventional automatics. This results in quicker, more direct shifts and a more engaging driving experience. The transmission is tuned for performance, with quick response times and the ability to hold gears during aggressive driving.
Driving Characteristics
The GLC 63 S delivers exhilarating performance. The 510 horsepower and 516 lb-ft of torque provide effortless acceleration, with a 0-60 mph time of just 3.6 seconds. The MCT transmission contributes to this performance, offering rapid gear changes and a connected feel. The 9-speed configuration provides a wide range of gear ratios, optimizing both acceleration and fuel efficiency. Compared to lower-powered GLC variants, such as the GLC 300, the 63 S offers a significantly more aggressive driving experience. While the GLC 300 prioritizes comfort and fuel economy, the 63 S is focused on performance and handling. The exhaust note is also dramatically different, with a more pronounced and aggressive sound thanks to the AMG performance exhaust system.
Equipment & Trim Levels
The GLC 63 S came standard with a comprehensive list of features, reflecting its premium positioning. Interior appointments included AMG sport seats upholstered in Nappa leather, a flat-bottom AMG steering wheel, and aluminum paddle shifters. Standard technology included the COMAND infotainment system with a large central display, navigation, and a premium sound system. Optional extras included features like a head-up display, a panoramic sunroof, and advanced driver-assistance systems such as adaptive cruise control and lane-keeping assist. Exterior styling cues included AMG-specific body styling, larger wheels and tires, and quad exhaust outlets.
Chassis & Braking
The GLC 63 S features a performance-tuned chassis designed to handle the increased power. The suspension utilizes AMG Ride Control, an adaptive damping system that allows the driver to adjust the firmness of the ride. The front suspension employs a multi-link design, while the rear suspension also utilizes a multi-link setup. Braking performance is provided by large, ventilated discs on all four wheels, with AMG-branded calipers. The braking system is designed to withstand repeated hard use and provide consistent stopping power. The 4MATIC+ all-wheel-drive system provides excellent traction in all weather conditions, distributing power between the front and rear axles as needed.
Market Reception & Comparison
The GLC 63 S was generally well-received by automotive critics, who praised its performance, handling, and luxurious interior. However, some reviewers noted that the ride could be firm, especially in the sportiest suspension settings. Fuel economy was also a concern, as expected for a high-performance SUV. Compared to its rivals, such as the Porsche Macan Turbo, the GLC 63 S offered a compelling combination of performance, luxury, and practicality. The Macan Turbo was often praised for its sharper handling, while the GLC 63 S offered a more spacious interior and a more comfortable ride. Reliability reports have been generally positive, with few major issues reported.
Legacy
The M177 engine family, including the version found in the GLC 63 S, has proven to be relatively robust and reliable. While maintenance costs are higher than those of lower-powered engines, the powertrain has generally held up well over time. On the used car market, the GLC 63 S commands a premium price due to its performance and exclusivity. It remains a desirable option for buyers seeking a high-performance luxury SUV. The combination of AMG engineering, a powerful V8 engine, and a practical SUV body style has cemented its place as a significant model in Mercedes-Benz’s history.
